DETAILED DESCRIPTION OF SELECTED EMBODIMENTS

Reference will now be made in detail to a preferred embodiment of the invention. An example of the preferred embodiment is illustrated in the accompanying drawings. While the invention will be described in conjunction with a preferred embodiment, it will be understood that it is not intended to limit the invention to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.

With the rapid deployment, proliferation, and technical advancement of mobile personal communication devices, such as cell phones, a user of these devices is presented with any number of ways to communicate with another user. For example, a user can send type a text message using, for example, Short Message Service-Point to Point (SMS-PP) protocol as defined in GSM recommendation 03.40 where messages are sent via a store-and forward mechanism to a Short Message Service Center (SMSC), which will attempt to send the message to the recipient and possibly retry if the user is not reachable at a given moment. Therefore, SMS-PP requires the use of a backend server to provide the necessary support for transmission of data between sender and receiver.

The invention, however, provides a mechanism whereby data is passed between a sender and receiver unit by way of voice channel only bypassing use of the data channel used in conventional arrangements. In this way, a sender can select that data which he/she desires to send to a receiver unit using by first converting the data into an appropriate vocal/voice format which is then forwarded to a receiver unit by way of the voice channel. Once received at the receiver unit, the vocalized data can be converted to an audio signal, which is then output by way of an audio output device (such as a speaker, earphone, etc.). This arrangement is particularly well suited for people having visual problems or in those situations where viewing the data on a small display screen (typical of most personal communication devices) is problematic.

In one embodiment, In a particular embodiment, the personal communication device is a pocket sized cell phone that in addition to the standard voice function of a telephone can support many additional services such as SMS for text messaging packet switching for access to the Internet and MMS for sending and receiving photos and video.

Accordingly, FIG. 1 shows an exemplary personal communication device 100 (such as a cell phone) in accordance with an embodiment of the invention. The cell phone 100 includes a processor 102 that pertains to a microprocessor or controller for controlling the overall operation of the cell phone 100 that stores data in a RAM 104 and a Read-Only Memory (ROM) 106. The ROM 106 can store programs, utilities or processes to be executed in a non-volatile manner whereas the RAM 104 provides volatile data storage such as currently called phone numbers, ring tones, etc. The cell phone 100 also includes a user input device 108 that allows a user to interact with the cell phone 100. For example, the user input device 108 can take a variety of forms, such as a button, keypad, dial, etc. Still further, the cell phone 100 includes a display 110 (screen display) that can be controlled by the processor 102 to display information to the user. A data bus can facilitate data transfer between at least the ROM 106, RAM 104, the processor 102, and a CODEC 112 that produces analog output signals for an audio output device 114 (such as a speaker). The speaker 114 can be a speaker internal to the cell phone 100 or external to the cell phone 100. For example, headphones or earphones that connect to the cell phone 100 would be considered an external speaker. A wireless interface 116 operates to receive information from the processor 102 that opens a channel (either voice or data) for transmission and reception typically using RF carrier waves.

FIG. 2 shows a system 200 having a cell phone 202 arranged to pass vocalized multimedia data to a receiver unit 204 in accordance with an embodiment of the invention. It should be noted that the system 200 can be used by any number of cell phones or other compatible personal communication devices and is not therefore limited to only the particular embodiment shown in FIG. 2. Accordingly, when the cell phone 202 is actively displaying multimedia data 206 on a display screen 208, a user has the option of having the cell phone 202 vocalize the displayed data (which in this example is a phone number “650 555-1234”) in order to be passed by way of a voice channel 210 to the receiver unit 204 (in this case another cell phone) or any number of other cell phones or compatible personal communication devices.

Once received at the cell phone 204, processing of the vocalized data can be performed based upon a prompted user request or based upon a pre-selected protocol. For example, once received at the cell phone 204, the vocalized phone number can be passed to an audio output device 212 that (in the case of a speaker) generates an audible rendition of the vocalized phone number. In another case (shown in FIG. 3), the vocalized phone number is forwarded to a voice mail server 300 where the receiver records the vocalized phone number as a voice mail message for subsequent playback. It should be noted that in this case, the sender can pre-select this option for those cases where the sender wishes to generate a simple text message and instead of having the text message displayed on the receiver's display screen, the vocalized text message is stored in the receiver's voice mail server.

FIG. 4 shows a flowchart illustrating a particular process 400 for transferring multimedia data over a voice channel in accordance with an embodiment of the invention. Accordingly, at 402, voice channel is opened or otherwise made available for transmission of the multimedia data. At 404, multimedia data is displayed on a display screen. In the described embodiment, various user selectable icons are available for selecting some or all of the displayed multimedia data. For example, if the displayed multimedia data is textual in nature (such as a phone number or short test message), a pointer can be used to point to and select the portion of the text to send. Therefore, at 406 a user selection of the displayed multimedia data (or portion thereof) is received along with a user prompt at 408 that causes the cell phone to vocalize the selected multimedia data in preparation for transmission over the available voice channel. At 410, the selected multimedia data is vocalized and transmitted over the voice channel at 412 to a receiver unit.

FIG. 5 shows a flowchart detailing a process 500 for receiving vocalized multimedia data in accordance with an embodiment of the invention. The process 500 begins at 502 by receiving the vocalized multimedia data over the voice channel. If, at 504, it is determined that there is no further processing, then the process 500 stops, otherwise, the vocalized multimedia data is further processed at 506. By further processing, it is meant that once the vocalized multimedia data is received, there are any number of additional processing that can be performed, such as passing the vocalized multimedia data to an output audio device (such as a speaker, headphone jack, etc.) for conversion to an audible version of the vocalized multimedia data. In some cases, default additional processing can be performed whereby any vocalized multimedia data received is automatically converted back to text and displayed and/or converted to an audible message.

For example, FIG. 6 shows a flowchart detailing a process 600 for forwarding the vocalized multimedia data to a voicemail server in accordance with an embodiment of the invention. The process 600 begins at 602 by (optionally) displaying the vocalized multimedia data and forwarding the vocalized multimedia data to a voice mail server at 604 and updating a voice mail indicator at 606 indicating that a new voice mail message has been recorded.

While this invention has been described in terms of a preferred embodiment, there are alterations, permutations, and equivalents that fall within the scope of this invention. It should also be noted that there are many alternative ways of implementing both the process and apparatus of the present invention. It is therefore intended that the invention be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention.
